Auto Scaling

Key Points Adds or removes capacity automatically in response to workload demand Used in cloud platforms, Kubernetes clusters, and distributed services Responds to metrics such as CPU, queue depth, request rate, or health Supports elasticity and resource efficiency Prevents overprovisioning…

Service Level Agreement

Key Points Defines measurable service commitments Used between providers and customers Often includes availability and response targets Supports accountability and operational planning Definition Service Level Agreement is a formal agreement that defines service targets, responsibilities, and performance expectations between parties.…

Cloud Migration

Key Points Moves workloads into cloud environments May involve data, apps, and networking Can be phased or lift-and-shift Common in modernization projects Requires careful operational transitions rather than simple workload copying Involves planning, transferring, validating, and stabilizing workloads Definition Cloud…

Cloud Computing

Key Points Provides on-demand computing resources Includes compute, storage, and networking services Supports elastic scaling and managed operations Foundational model for modern digital infrastructure Enables remote provisioning from managed environments Supports enterprise IT, software development, analytics, and collaboration Definition Cloud…

Metrics

Key Points Provide numerical evidence for state or performance Used in monitoring and analysis Can describe technical or business behavior Important in operations and assurance Enable data-driven operational decisions rather than assumption-based decisions Require careful selection to avoid measuring the…

Vendor-Agnostic Integration

Key Points Reduces dependence on a single supplier Uses standardized or portable interfaces Common in multi-vendor operational environments Enables systems from different vendors to exchange data or functions Reduces lock-in and makes mixed environments easier to operate Definition Vendor-Agnostic Integration…

Bridge to Network Integration

Key Points Connects bridge operations with network services Supports navigation, reporting, and data exchange Requires security and segregation controls Preserves safety boundaries and operational integrity Enables data sharing while preventing network interference with bridge-critical functions Definition Bridge to Network Integration…

Hybrid Cloud

Key Points Combines private and public cloud environments Supports workload placement across environments Used for flexibility and governance Requires integration and network coordination Enables organizations to use both dedicated and shared cloud resources together Definition Hybrid Cloud is a cloud…

Oversubscription

Key Points Allocates shared capacity above guaranteed baseline Common in networks and cloud systems Relies on statistical concurrency assumptions Can improve utilization and reduce costs but increases congestion risk Deliberate capacity strategy that trades guaranteed headroom for higher utilization Failure…

Key Management

Key Points Covers the full key lifecycle from generation through revocation Supports encryption and authentication systems Requires secure storage and access control Critical in security operations and compliance Failure modes include key exposure, lost keys, expired keys, and broken trust…
